A recently discovered Linux malware with backdoor capabilities has flown under the radar for years, allowing attackers to harvest and exfiltrate sensitive information from compromised devices. 

The backdoor, dubbed RotaJakiro by researchers at Qihoo 360's Network Security Research Lab (360 Netlab), remains undetected by VirusTotal's anti-malware engines, although a sample was first uploaded in 2018.
